Answer:
A and C
Step-by-step explanation:
A is correct because converting the percentage to decimal form will give you the value of that percentage, and 62% will be the same as 0.62 in decimal form.
C is the same in a less simplified form because 62/100 = 0.62, so it is the same as A when you convert it to decimal form, 0.62 · 45.
Answer:
The sixth term of the binomial expansion is;
10C5 (5y)^5 (3)^5
Step-by-step explanation:
Here, we want to select which of the options represent the 6th term of the binomial expansion;
(5y + 3)^10
We should know that while the powers of 5y will be increasing, the powers of 3 will be decreasing.
We can write the terms as follows;
10C0(5y)^10(3)^0 + 10C1(5y)^9(3)^1 + 10C2(5y)^
8(3)^2 + 10C3(5y)^7(3)^3 + 10C4(5y)^6(3)^4 + 10C5(5y)^5(3)^5 + ............

Answer:
Option C
Step-by-step explanation:
n = 81
s2 = 625
H0: σ2 = 500
Ha: σ2 ≠ 500
Test Statistics X^2 = (n-1)s^2/ σ2 = (81-1)*625/500
X^2 = 100
P value = 0.0646 for degree of freedom = 81-1 = 80
And X^2 = 100
At 95% confidence interval
Alpha = 0.05 , p value = 0.0646
p < alpha, we will reject the null hypothesis
At 95% confidence, the null hypothesis
